The length of the contour curve of any surface of a single lens in the range of the maximum effective radius affects the surface correction aberration and the optical path difference between the fields of view. The longer the profile curve length, the better the ability to correct the aberration, but at the same time It will increase the difficulty in manufacturing, so it is necessary to control the length of the profile curve of any surface of a single lens within the maximum effective radius, in particular to control the profile length (ARS) and the surface within the maximum effective radius of the surface. The proportional relationship (ARS/TP) between the thicknesses (TP) of the lens on the optical axis.

For any surface of any lens, the profile curve length within a half of the entrance pupil diameter (HEP) affects the ability of the surface to correct aberration and differences between optical paths of light in different fields of view. With longer profile curve length, the ability to correct aberration is better. However, the difficulty of manufacturing increases as well. Therefore, the profile curve length within a half of the entrance pupil diameter (HEP) of any surface of any lens has to be controlled. The ratio between the profile curve length (ARE) within a half of the entrance pupil diameter (HEP) of one surface and the thickness (TP) of the lens, which the surface belonged to, on the optical axis (i.e., ARE/TP) has to be particularly controlled.

DETAILED DESCRIPTION OF THE INVENTION

An optical image capturing module of the present invention includes a structural design and an optical design, wherein structural embodiments will be described first.

As shown in FIG. 1A, an optical image capturing module according to a first structural embodiment of the present invention includes mainly includes a circuit assembly and a lens assembly. The circuit assembly includes an image sensing component S, a sensor holder SB, and a circuit substrate EB. A maximum value of a minimum length of an outer periphery of the image sensing component S which is perpendicular to a plane of an optical axis of the lens assembly is denoted by LS. In the current embodiment, the image sensing component S is fixed on the circuit substrate EB in a Chip On Board (COB) package. More specifically, the circuit substrate EB has a plurality of circuit contacts EP thereon; the image sensing component S has a first surface S1 and a second surface S2, wherein the first surface S1 is connected to the circuit substrate EB, and the second surface S2 has a sensing surface and a plurality of image contacts IP. Each of the image contacts IP is electrically connected to one of the circuit contacts EP on the circuit substrate EB via a plurality of signal transmission elements SC1. In the current embodiment, each of the signal transmission elements SC1 is a gold wire. The sensor holder SB is disposed on the circuit substrate EB and on the second surface S2 of the image sensing component S, and covers the circuit contacts EP and the image contacts IP, wherein the signal transmission elements SC1 is embedded in the sensor holder SB. In this way, when an image optical signal is sensed by the sensing surface of the image sensing component S and is transformed into an electrical signal, the electrical signal could be sent to the circuit contacts EP via the image contacts IP and the signal transmission elements SC1, so that the circuit contacts EP could transmit the electrical signal to other external components for subsequent processing.

The lens assembly includes a fixed base FB1, a movable base MB1, a lens group L, and an IR-cut filter IR1. In the current embodiment, the fixed base FB1 is made of plastic material and is opaque, and has a focusing hole penetrating through both ends of the fixed base FB1, so that the fixed base FB1 is hollow. The fixed base FB1 is disposed on the sensor holder SB, so that the focusing hole directly faces the image sensing component S. The fixed base FB1 has a predetermined thickness TH1, and a maximum value of a minimum length on a periphery of the lens holder LH1 perpendicular to the optical axis of the lens group L is denoted by PhiD. The movable base MB1 has a receiving hole penetrating through both ends of the movable base MB1, so that the movable base MB1 is hollow, wherein the receiving hole directly faces the sensing surface of the image sensing component S. More specifically, the movable base MB1 includes an inner holder LH1 and a lens barrel B1, wherein the inner holder LH1 is disposed in the fixed base FB1 and is located in the focusing hole, and is controllable to move relative to the fixed base FB1. In addition, the inner holder LH1 has an inner through hole DH1 penetrating through both ends of the inner holder LH1 to be hollow. The lens barrel B1 is disposed in the inner holder LH1 and is located in the inner through hole DH1, and is capable of being driven by the inner holder LH1 to move relative to the fixed base FB1. The lens barrel B1 has the receiving hole penetrating through both ends of the lens barrel B1, so that the lens barrel B1 is hollow. The lens barrel B1 has a predetermined thickness TH2, and a maximum value of a minimum length on a periphery of the lens barrel B1 perpendicular to the optical axis of the lens group L is denoted by PhiC. The lens group L is disposed in the lens barrel B1 to directly face the sensing surface of the image sensing component S. In the current embodiment, a glue is coated between the lens barrel B1 and the inner holder LH1, and the lens barrel B1 and the inner holder LH1 are fixed to each other via the glue, so that the lens barrel B1 is disposed in the inner holder LH1 and is fixed in the inner through hole DH1.

The lens group L includes at least two lenses with refractive power, and optical embodiments will be described in detail later. The lens group L is disposed on the lens barrel B1 of the movable base MB1 and is located in the receiving hole. In addition, an image plane of the lens group L is adjustable to be located on the sensing surface of the image sensing component S along with a movement of the movable base MB1, wherein the optical axis of the lens group L overlaps with a central normal of the sensing surface, so that light could pass through the lens group L in the receiving hole and could be projected onto the sensing surface. Moreover, a maximum diameter of an image-side surface of a lens of the lens group L closest to the image plane is denoted by PhiB, and a maximum effective diameter of the image-side surface of the lens of the lens group L closest to the image plane (i.e., the image space) could be also called optical exit pupil, and is denoted by PhiA.

The IR-cut filter IR1 is disposed in the fixed holder FB1 and is located above the image sensing component S, thereby to filter out an excess infrared in the image light passing through the lens group L, enhancing the image quality.

It is worth mentioning that, in order to overlap the optical axis of the lens group L with the central normal of the sensing surface of the image sensing component S, an outer side of the lens barrel B1 of the optical image capturing module of the current embodiment is not completely in contact with an inner periphery of the inner holder LH1, thereby to leave a slight gap, so that a curable glue could be coated between the inner holder LH1 and the lens barrel B1 in advance, and the optical axis of the lens group L and the central normal of the image sensing component S could be adjusted to be overlapped with each other, and then the curable glue is cured to fix the lens barrel B1 to the inner holder LH1, that is, an active alignment assembly is carried out.

where z is a depression of the aspheric surface; k is conic constant; c is reciprocal of the radius of curvature; and A4, A6, A8, A10, A12, A14, A16, A18, and A20 are high-order aspheric coefficients.

In the optical image capturing module, the lenses could be made of plastic or glass. The plastic lenses may reduce the weight and lower the cost of the optical image capturing module, and the glass lenses may control the thermal effect and enlarge the space for arrangement of the refractive power of the optical image capturing module. In addition, the opposite surfaces (object-side surface and image-side surface) of the first to the seventh lenses could be aspheric that could obtain more control parameters to reduce aberration. The number of aspheric glass lenses could be less than the conventional spherical glass lenses, which is helpful for reduction of the height of the optical image capturing module.

When the lens has a convex surface, which means that the surface is convex around a position, through which the optical axis passes, and when the lens has a concave surface, which means that the surface is concave around a position, through which the optical axis passes.

The optical image capturing module of the present invention could be applied in a dynamic focusing optical image capturing module. It is superior in the correction of aberration and high imaging quality so that it could be allied in lots of fields.

The optical image capturing module of the present invention could further include a driving module to meet different demands, wherein the driving module could be coupled with the movable base or the lenses to move the lenses. The driving module could be a voice coil motor (VCM), which is used to move the lens for focusing, or could be an optical image stabilization (OIS) component, which is used to lower the possibility of having the problem of image blurring which is caused by subtle movements of the lens while shooting.

To meet different requirements, at least one lens among the first lens to the seventh lens of the optical image capturing module of the present invention could be a light filter, which filters out light of wavelength shorter than 500 nm. Such effect could be achieved by coating on at least one surface of the lens, or by using materials capable of filtering out short waves to make the lens.

To meet different requirements, the image plane of the optical image capturing module in the present invention could be either flat or curved. If the image plane is curved (e.g., a sphere with a radius of curvature), the incidence angle required for focusing light on the image plane could be decreased, which is not only helpful to shorten the length of the optical image capturing module (TTL), but also helpful to increase the relative illuminance.

We provide several optical embodiments in conjunction with the accompanying drawings for the best understanding. In practice, the optical embodiments of the present invention could be applied to other structural embodiments.

Second Optical Embodiment

As shown in FIG. 3A and FIG. 3B, an optical image capturing module 20 of the second optical embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 210, a second lens 220, a third lens 230, an aperture 200, a fourth lens 240, a fifth lens 250, a sixth lens 260, a seventh lens 270, an IR-cut filter 280, an image plane 290, and an image sensor 292.

The first lens 210 has negative refractive power and is made of glass. An object-side surface 212 thereof, which faces the object side, is a convex spherical surface, and an image-side surface 214 thereof, which faces the image side, is a concave spherical surface.

The second lens 220 has negative refractive power and is made of glass. An object-side surface 222 thereof, which faces the object side, is a concave spherical surface, and an image-side surface 224 thereof, which faces the image side, is a convex spherical surface.

The third lens 230 has positive refractive power and is made of glass. An object-side surface 232, which faces the object side, is a convex spherical surface, and an image-side surface 234, which faces the image side, is a convex spherical surface.

The fourth lens 240 has positive refractive power and is made of glass. An object-side surface 242, which faces the object side, is a convex spherical surface, and an image-side surface 244, which faces the image side, is a convex spherical surface.

The fifth lens 250 has positive refractive power and is made of glass. An object-side surface 252, which faces the object side, is a convex spherical surface, and an image-side surface 254, which faces the image side, is a convex spherical surface.

The sixth lens 260 has negative refractive power and is made of glass. An object-side surface 262, which faces the object side, is a concave spherical surface, and an image-side surface 264, which faces the image side, is a concave spherical surface. Whereby, the incident angle of each view field entering the sixth lens 260 could be effectively adjusted to improve aberration.

The seventh lens 270 has negative refractive power and is made of glass. An object-side surface 272, which faces the object side, is a convex surface, and an image-side surface 274, which faces the image side, is a convex surface. It may help to shorten the back focal length to keep small in size, and may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The IR-cut filter 280 is made of glass and is disposed between the seventh lens 270 and the image plane 290. The IR-cut filter 280 gives no contribution to the focal length of the optical image capturing module.

The parameters of the lenses of the second optical embodiment are listed in Table 3 and Table 4.

As shown in FIG. 4A and FIG. 4B, an optical image capturing module of the third optical embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 310, a second lens 320, a third lens 330, an aperture 300, a fourth lens 340, a fifth lens 350, a sixth lens 360, a seventh lens 370, an IR-cut filter 380, an image plane 390, and an image sensor 392.

The first lens 310 has negative refractive power and is made of glass. An object-side surface 312 thereof, which faces the object side, is a convex spherical surface, and an image-side surface 314 thereof, which faces the image side, is a concave spherical surface.

The second lens 320 has negative refractive power and is made of glass. An object-side surface 322 thereof, which faces the object side, is a concave spherical surface, and an image-side surface 324 thereof, which faces the image side, is a convex spherical surface.

The third lens 330 has positive refractive power and is made of plastic. An object-side surface 332 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 334 thereof, which faces the image side, is a convex aspheric surface. The image-side surface 334 has an inflection point.

The fourth lens 340 has negative refractive power and is made of plastic. An object-side surface 342, which faces the object side, is a concave aspheric surface, and an image-side surface 344, which faces the image side, is a concave aspheric surface. The image-side surface 344 has an inflection point.

The fifth lens 350 has positive refractive power and is made of plastic. An object-side surface 352, which faces the object side, is a convex aspheric surface, and an image-side surface 354, which faces the image side, is a convex aspheric surface.

The sixth lens 360 has negative refractive power and is made of plastic. An object-side surface 362, which faces the object side, is a convex aspheric surface, and an image-side surface 364, which faces the image side, is a concave aspheric surface. The object-side surface 362 has an inflection point, and the image-side surface 364 has an inflection point. It may help to shorten the back focal length to keep small in size. Whereby, the incident angle of each view field entering the sixth lens 360 could be effectively adjusted to improve aberration.

The IR-cut filter 380 is made of glass and is disposed between the sixth lens 360 and the image plane 390. The IR-cut filter 390 gives no contribution to the focal length of the optical image capturing module.

The parameters of the lenses of the third optical embodiment are listed in Table 5 and Table 6.
